FIELD OF USE

The present disclosure relates generally to footwear, and more particularly, to a double shoe combination footwear comprising an inner shoe and outer shoe, wherein the inner shoe is adapted to fit within the shoe cavity of the outer shoe and may be entirely concealed within the outer shoe, regardless of the shape of the upper of the outer shoe.

BACKGROUND

In general, shoes are routinely worn by many people around the world. The type of shoe worn at a particular time and in a particular place by a particular wearer can depend on a number of factors. For example, the wearer can factor in comfort, design, social setting and even status when picking the appropriate shoe.

In many instances, shoes that would be appropriate for one setting would be inappropriate for another setting. For example, dance shoes that would be appropriate during a dance recital but may not be appropriate for a more formal setting, such as a reception or dinner. What this means is that if the wearer is leaving one social setting to a different social setting without returning home or to where his/her shoes are located, he/she may be required to carry multiple pairs of shoes.

Unfortunately, this can lead to several problems. For example, the wearer must change her shoes which may draw attention to the inappropriate shoes. Thus, if the wearer wears high heels at a formal event but later changes into flats, this may inadvertently draw attention from others. Additionally, the wearer must find a place to store the extra shoes. This may not always be a problem, but may be inconvenient for the wearer to carry a second pair of shoes to each location. Carrying and storing the second pair of shoes may also cause the wearer to simply forget the second pair of shoes.

Finally, wearing one pair of shoes may be uncomfortable for the wearer at certain occasions. For example, high heeled women's shoes tend to lack significant amounts of padding, which can lead to blisters or other sores on the foot of the wearer, especially if worn for long periods of time. Although the wearer may have a comfortable pair of shoes lying close at hand, the wearer may not be able to wear those shoes due to social restrictions.

Accordingly, there is a need for footwear that provides the wearer with a comfortable alternative. Preferably, the footwear is a double shoe combination footwear, comprising two pair of shoes, wherein a second pair of shoes fits within the shoe cavities of the first pair of shoes. Preferably, the second pair of shoes or inner shoes are completely concealed within the first pair of shoes when both pair of shoes are simultaneously worn by the wearer. Preferably, the first pair of shoes serves as a storage source for the second, inner pair of shoes.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of various aspects of one or more embodiments. However, the one or more embodiments may be practiced without some or all of these specific details. In other instances, well-known procedures and/or components have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

While some embodiments are disclosed herein, still other embodiments will become obvious to those skilled in the art as a result of the following detailed description. These embodiments are capable of modifications of various obvious aspects, all without departing from the spirit and scope of protection. The Figures, and their detailed descriptions, are to be regarded as illustrative in nature and not restrictive. Also, the reference or non-reference to a particular embodiment shall not be interpreted to limit the scope of protection.

In the following description, certain terminology is used to describe certain features of one or more embodiments. For purposes of the specification, unless otherwise specified, the term “shoe”, as used herein, refers to any footwear intended to protect and provide comfort the human foot and comprises at least an upper and a rigid, stiff outsole attached to the upper as a separate piece. Thus, any footwear lacking an outsole and/or that cannot generally be worn comfortably outdoors while being subject to the elements (e.g., dirt, dust, water, rocks, heat, sharp objects), are not shoes for purposes of this specification. Examples of such footwear that are not shoes includes at least, socks, stocking, hosiery, shoe liners, and removable lining. For purposes of this disclosure, slippers, house slippers, and sandals are also not shoes as defined herein.

As used herein, the term “fastener” refers to a structure or method which is capable of at least partially holding and securing the second shoe (i.e., inner shoe) within the shoe cavity of the first shoe (i.e., outer shoe). Examples of fasteners may include, without limitation, snaps, hooks, straps, cords, hook and loop fasteners (i.e., Velcro®), buttons, drawstrings, buckles, clasps, and zippers.

As used herein, the term “heel” refers to any solid, raised base or support constructed of stiff material such as leather, wood, rubber, and the like, attached to the sole portion of a shoe or boot beneath the back portion of the foot. Examples of shoes with heels include, without limitation, pointed-toes (e.g., pointed-toe mary jane, pointed-toe t-strap, pointed-toe d'orsay, pointed-toe pump, pointed-toe slingback), kitten heels (e.g., kitten heel peep-toe d'orsay), wedges (e.g., closed-toe wedge, peep-toe wedge, platform wedges, peep-toe ankle strap platform wedges), mules, pumps (e.g., almond-toe pumps, round-toe pumps, platform pumps), peep-toes (e.g., peep-toe platforms, peep-toe platform slingbacks, peep-toe ankle strap platforms, peep-toe mary janes), slingbacks (e.g., platform slingbacks), platforms (e.g., mary jane platforms, t-strap peep-toe platforms, t-strap peep-toe d'orsay platforms, heel-less ankle strap peep-toe platforms, ankle strap platforms), clear heels, spool heels, and stiletto heels.

As used herein, the term “boot” refers to a covering of leather, rubber, or the like, for the foot and at least a portion of the wearer's leg above the ankle. Examples of boots include, without limitation, ballet boots, Beatle boots, cowboy boots, fashion boots, kinky boots, knee high boots, platform boots, thigh high boots, and winklepickers.

As used herein, the term “plantable material” refers to any eco-friendly material such as biodegradable material with seeds embedded into the material. Preferably, the plantable material may be planted into the ground for growing plants and may include, without limitation, seed paper.

As used herein, the terms “approximately” and “about” generally refer to a deviance of within 5% of the indicated number or range of numbers. In one embodiment, the term “approximately” and “about”, refer to a deviance of between 1-10% from the indicated number or range of numbers.

As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, in one embodiment, an object that is “substantially” the same in size, shape, and design would mean that the object is either completely the same/identical in size, shape, and design or nearly completely the same/identical in size, shape, and design. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is also equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result.

FIG. 1 is an illustration of one embodiment of a double shoe combination footwear with a concealed inner shoe. As shown in FIG. 1, one embodiment of the double shoe combination footwear 100 may comprise a first shoe 12 (i.e., outer shoe) and a second shoe 13 (i.e., inner shoe). FIG. 1 shows that the double shoe combination footwear 100 may be configured for a user to wear a first shoe 12 inside a second shoe 13. Specifically, the user may insert the second shoe 13 within the shoe cavity of the first shoe 12, and then the user may then insert his/her foot within the shoe cavity of the second shoe 13 without removing the second shoe 13 from the first shoe 12. Preferably, the second shoe 12 fits snugly within the shoe cavity of the first shoe 13, such that the second shoe 13 does not shift or move within the shoe cavity of the first shoe 12. In an embodiment, the second shoe 13 can provide padding for the outer shoe, and, in a preferred embodiment, the first shoe 12 is preferably capable of entirely or at least substantially concealing the second shoe 12.

FIG. 1 shows that the double shoe combination footwear 100 may comprise a first shoe 12 and a second shoe 13, both of which are intended to protect and comfort the human foot while doing various activities. Thus, the first shoe 12 and second shoe 13 may be constructed of any stiff and rigid material, including without limitation, leather, wood, canvas, rubber, plastics, and/or other materials.

FIG. 1 also shows that one embodiment of the first shoe 12 may comprise: a first outsole 2, first upper 5, first insole 6, and heel 1. The first outsole 2 is generally the bottom surface or layer of the sole that contacts directly with the ground. Because the foot of the user is generally vulnerable to environmental hazards such as sharp objects, heated grounds, and/or slippery surfaces, the first shoe 12 is generally constructed with the first outsole 2 to help protect the foot of the user. The first outsole 2 may be constructed of any material, including without limitation, leather, resin rubber, natural rubber or a synthetic material such as polyurethane. The first outsole may be constructed as a single piece or may be an assembly of separate pieces of various materials. For example, the heel 1 of the outsole 2 may comprise a rubber plate or tip positioned at the bottom of the heel 1 for durability and traction, while the front of the first outsole 2 may be constructed of leather for style. Specialized shoes may also have modifications on this design. For example, athletic or cleated shoes for soccer, rugby, baseball and golf shoes may have spikes embedded in the first outsole 2 to grip the ground.

FIG. 1 further shows that the first shoe 12 may comprise a first upper 5, which is generally the upper portion of the shoe above the sole of the shoe. The first upper 5 is generally configured to cover the upper of the second shoe (i.e., second upper 10) but may also be configured to cover the toes, the top of the foot, the sides of the foot, and/or the back of the heel of the wearer. In one embodiment, the first upper 5 may comprise the upper portion of the first shoe above the sole of the first shoe 12 and may help hold and secure the first shoe onto the foot. In the simplest cases, such as sandals or flip-flops, this may comprise a few straps for holding the sole in place. Closed footwear, such as boots, trainers and most men's shoes, may have a more complex upper and may be decorated in a certain style to look attractive. The first upper 5 may comprise laces, fasteners (e.g., hook and loop fasteners), straps or other devices for securing the first upper 5 around the foot of the user.

As discussed above, FIG. 1 also shows that the first shoe 12 may comprise a heel 1. The heel 1 may comprise a top piece, which is located beneath the upper surface or layer of the sole that contacts with the user's foot the heel portion and is configured to come into contact with the ground. Preferably, the heel 1 is configured to support the weight and heel of the foot and is generally intended to elevate the user or make the user look taller. The heel 1 may also comprise one or more embellishments for design, such as in high heel shoes. In an embodiment, the heel 1 may be at least 1.5 inches in height, as shown in FIG. 1. An example of a shoe with a heel of at least 1.5 inches may be a shoe with a stiletto heel.

FIG. 1 also shows that the first shoe 12 may comprise a first insole 6, which is generally the interior bottom portion of a shoe and upper surface of the sole. The first insole 6 is generally configured to sit directly beneath the foot under the footbed or sock liner and may be configured to contact the second outsole 9 of the second shoe 13. Preferably, the first insole 6 is located above the first outsole 2 and may be configured to protect and cushion the foot of the user. The first insole 6 may be constructed of various materials, including without limitation, cellulosic paper board or synthetic non-woven insole board. Extra material may also be added to the first insole 6 for comfort to: (1) help control the shape, moisture, or smell of the shoe; (2) help deal with defects in the natural shape of the foot; or (3) orthotically position the foot during standing or walking.

As discussed above, FIG. 1 further shows that the double-shoe combination footwear 100 may comprise a second shoe 13. One embodiment of the second shoe 13 may comprise: a second outsole 9 and a second upper 10. The second outsole 9 is generally the bottom surface or layer of the sole that contacts directly with the ground and is generally constructed of stiff, resilient materials to protect the foot of the user from environmental hazards such as sharp objects, heated grounds, and/or slippery surfaces. The second outsole 9 is also preferably impermeable to protect the wearer from wet surfaces. The second outsole 9 may be constructed of any material, including without limitation, leather, resin rubber, natural rubber or a synthetic material such as polyurethane. The second upper 10 is generally the upper portion of the second shoe 13 above the sole of the shoe and may generally be configured to cover the toes of the wearer, the top of the foot, the sides of the foot, and/or the back of the heel. In one embodiment, the second upper 10 may comprise the upper portion of the second shoe above the sole of the second shoe 13 and may help hold and secure the second shoe 13 onto the foot.

In this embodiment, the second shoe 13 may be configured to fit inside the first shoe 12. Specifically, the second shoe 13 may be inserted in the shoe cavity of the first shoe 12 and is preferably adapted to fit snugly and rest matingly above the first insole 6 and within the upper 5 of the first shoe 12. The second shoe 13 may also be lightweight compared to the first shoe 12.

In one embodiment, the user may remove the first shoe 12 while continuing to wear the second shoe 13. Alternatively, the user may remove the second shoe 13 from the first shoe 12 and wear the first shoe 12 separately without the second shoe 13 inside the first shoe 12. Further, the user may wear both the second shoe 13 and the first shoe 12 if desired, such that the user may insert his/her foot into the second shoe 13 while the second shoe 13 is stored within the first shoe 12.

In various embodiments, the second shoe 13 may be any shoe with an outsole that is stiffer than the upper. Preferably, the second shoe 13 is capable of being inserted into the first shoe 12. In one embodiment, the second shoe 13 may be a canvas or cloth shoe that can bend and flex while being inserted into or removed from the first shoe 12. In another embodiment, the second shoe 13 such as a canvas shoe may be constructed with leather and/or synthetic materials. The second shoe 13 may also comprise a heel, or may be a flat shoe as desired by the user. In a preferred embodiment, the second upper 10 of the second shoe 13 is substantially similar or identical to the first upper 5 of the first shoe 12.

In another embodiment, the second shoe 13 may be a ballet shoe. Ballet shoes or ballet slippers, are generally any lightweight shoes designed specifically for ballet dancing. Ballet shoes may be constructed of various materials, including without limitation, soft leather, canvas, or satin, and may have flexible, thin soles. Generally, ballet shoes may fit very closely to the user's foot, for safety and for retaining maximum flexibility. For example, the second shoe 13 may be a pointe shoe, which is generally a ballet shoe with a box portion located at the front end of the shoe for encasing and supporting the dancer's toes and a shank (i.e., a piece of rigid material that serves to stiffen the sole so as to provide support for the arch of the en pointe foot).

When the second shoe 13 is removably inserted into the first shoe 12, the second outsole 9 of the second shoe 13 may function as an additional insole 6 for the first shoe 12. Alternatively, the second outsole 9 may form a sockliner or midsole if the first shoe 12 already includes a first insole 6. Thus, the first shoe 12 is constructed and arranged to receive the second shoe 13, and to accommodate the outsole 9 of the second shoe 13 within the first shoe 12, such that the second shoe 13 does not shift or move within the first shoe 12. In other words, the second shoe 13 preferably fits within the shoe cavity of the first shoe 12 with minimal space or gaps between the first shoe 12 and second shoe 13.

One of skill in the art will appreciate that the second shoe 13 is preferably nearly the same size and shape as the inner cavity of the first shoe 12. Specifically, the second shoe 13 may comprise a second outsole 9, second insole 11, and a second upper 10, which are mostly or completely hidden by the first shoe 12. Specifically, when both the second shoe 13 is inside the shoe cavity of the first shoe 12, the outer surface of the second upper 10 of the second shoe 13 is preferably hidden or concealed by the first shoe 12. This is especially true, when the first shoe 12 and second shoe 13 are worn simultaneously by the same foot by the user. For example, when inserted into the first shoe 12, the periphery of the second shoe 13 fits snugly within the first shoe 12. Further, the first upper 5 is sized and designed to accommodate a user's foot within the first shoe 12 while the second shoe 13 is disposed within the first shoe 12. In one embodiment, the second shoe 13 is substantially identical in size and shape.

FIG. 1 additionally shows that the second shoe 13 can be sized to be inserted in the first shoe 12. In particular, the shoe cavity created by the first upper 5 of the first shoe 12 is preferably large enough to accommodate and receive snugly the second shoe 13. In particular, the shoe cavity created by the first upper 5 of the first shoe 12 is approximately the same size and shape as the external shape and size of the second shoe 13.
